VVAL'IER B. MANNY, OFST. LOUIS, MISSOURI.

CIRCUIT-CLOSER.

SPECIFICATION forming part `of Letters Patent No. 354,919, dated December 28, 1886.

Application filed July 3, 1886. Serial No. 207,027. (No model.)

.To u/.ZZ whom it may concern:

Be it known that I, WALTER B. MANNY, a citizen of the United States, residing in the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Electric-Bell DoorKnockers, of whichthe following is a full, clear, and exact description.

My invention relates to doorknockers, combined with means for ringing an electric bell, and has for its object to enable a bell to be rung by the operation of the knocker, instead of separately, as heretofore.

On the accompanying drawings, Figure lis a side sectional View of a door-knoclier and its appurtenances constructed and arranged according to my invention; Fig. 2, a front secl tional View, and Fig. 3 a front elevation, re-

spectively, of the same, like letters of reference denoting like parts in all the figures.

c represents a door-knocker, which is swung or hinged in bearings b, carried by and projecting from the knocker-plate c, the latter being made of brass or other' suitable metal, formed with the ornamental head d, and screwed or'otherwise fixed to the door e in the ordinary manner.

Above the knocker a is arranged a flat steel or other metal spring, f, which projects froln the inside ofV the ornamental head d, (or from some other convenient part of the plate 0,) to which it is secured, and insulated therefrom by a piece of vulcanized rubber or other suitable material, g. From the ilat spring'f an insulated wire, z', extends through the doors toa suitable battery for generating an electric current, the other Wire, j, of this battery being attached on the inside ofthe door e to the knocker-plate c by the bolt k, or otherwise, as found most convenient.

On the hinged portion of the knocker a, be-

tween its bearings b and immediately in front of the flat springf, is an arm or lever, 71 which normally, or when the knoclrer a is not in use and resting against the knockerplate c, as shown in full lines, Fig. l, is out of contact with the4 flat springf.

On lifting the knocker et from its plate c the arm or lever h will come in contact with and displace the iiat spring f into the position shown by dotted lines in Fig. l, and in so do- 5o ing will close the circuit ij, and ring an electric y bell placed thereon. On bringing down the knocker c onto the plate c the arm or lever h is returned to its normal position, or out of contact with the ilat spring f, and the circuit t' j being thereby broken the bell will cease to ring, and the knocker c sound; or, in lieu of a iiat spring, f, I may use any other suitable metal surface for insuring the proper contact therewith of the arm or lever h.

I am aware that it is not new to connect the lnoeker on the same circuit with an electrical. bell in such manner that when the knocker is set in motion it also rings the bell, as is described in. English Letters Patent No. 8,622, of 1885, and I do not desire to claim the same, broadly.

I claini-` f The door-knocker a, formed with an arm or lever, h, in combination with spring knocker- 7o plate c, and wires t' j from an electric battery, substantially as shown, and for the purpose described.

In testimony whereof I affix my signature, in y presence of two witnesses, this 29th day of 75 June, 1886;

WALTER B. MANNY.
